Side effects of whey protein powder

Leah DeitzUpdated November 21, 2016

Whey is a protein derived from milk during the fermenting process. It can be consumed in either supplement or powdered form and is used in many consumer products including infant formula and various food items. The protein content associated with whey is beneficial for everyone from bodybuilders to infants. As a protein, it is an asset for muscle building and weight loss and is easier to digest than other forms of protein. Whey is known for its hunger satisfying capacity as well as immune boosting properties. However, excess protein consumption is associated with some health concerns and whey is specifically known to have some side effects.

Fatigue

Protein content is often associated with energy. But, whey consumption can cause fatigue if not supported by an otherwise healthy diet. Whey should be consumed in conjunction with complex carbohydrates.

Diarrhoea

Infants are specifically prone to diarrhoea caused by excess protein that the body can not process.

Headaches

Whey protein contains casein, a major trigger for migraines and other types of headaches.

Bloating

Excessive amounts of protein and whey are generally associated with bloating and flatulence.

Protein Intolerance

Just like lactose intolerance, many people develop protein intolerance. Whey can cause an immune system response which generally results in excess mucous production.
